Nitrogen (N2)

Nkọwa dị mkpirikpi:

Nitrogen (N2) bụ akụkụ bụ isi nke ikuku ụwa, na-aza 78.08% nke mkpokọta. Ọ bụ enweghị agba, enweghị isi, enweghị ụtọ, anaghị egbu egbu na ọ fọrọ nke nta ka ọ bụrụ gas inert kpamkpam. Nitrogen anaghị enwu ọkụ, a na-ewere ya dị ka gas na-egbu egbu (ya bụ, iku ume nitrogen dị ọcha ga-eme ka ahụ mmadụ ghara inwe oxygen). Nitrogen anaghị arụ ọrụ kemịkalụ. Ọ nwere ike meghachi omume na hydrogen iji mepụta amonia n'okpuru okpomọkụ dị elu, nrụgide dị elu na ọnọdụ ndị na-akpali akpali; ọ nwere ike jikọta ya na oxygen ka ọ bụrụ nitric oxide n'okpuru ọnọdụ mwepu.
